Dear Vapor Talk Friends,

I am a newbie.Brand New.This is my first post after Introduction. I hope I am not doing anything wrong. I read quite a bit of new user info, but in case I missed something. I apologize and I can take direction to an area where it might be better for me to ask this question. 

Looking for opinion/knowledge of e-liquid exposure to extreme heat over time & its' affects..ie. taste, color, texture/consistency, etc.

Please & Thank you in advance. 

This is what I am looking for direction on. I placed an order on the 1st of the month. The package of e-liquid was lost by the carrier. We have been living in temperatures of 70 in the AM and upper 90's in the afternoon on. I can't imagine the temperature in the delivery trucks. I got that order 5 days later because the carrier told me they lost the package and they they said they determined that the package got delivered incorrectly, but they got it back & should be at my home within no time. I got the package. I tried some of the e-liquids and something was way off on one. The color is usually dark, but it arrived totally opaque and the taste was totally different then when I had ordered it so many, many times in the past. The others arrived slightly darker and it just seems like the taste is off. The carrier has taken responsibility and the vendor has gone above and beyond when it was not their fault, I am just wanting to learn from other what extreme heat does to e-liquid over a period of days. No complaining. I would just like to learn and maybe get suggestions about this experience & best methods of large quantity storage.

Thanks again, NfinAt

Over time the nicotine oxidizes, which turns dark. The best way to store mixed juice is in the refrigerator. There have been reports that juice kept in the freezer will last for years. As far as what heat does, some people steep their juice with heat, others can tell you about that. I hope this answers your questions.

My experience is that excessive heat deteriorates juice pretty fast, both in color and taste.  Im sure it varies by juice.  Generally keeping them at room temp or below seems to be ok but even a day or two in a hot car or something is pretty bad. You may have even noticed your juice darkening in a tank from atomizer heat (even more so with sub ohm). 

I haven't looked at any studies but I would think with these food grade flavorings that we do run the risk of it going rancid pretty quick with excessive heat.

I'm thinking our resident mixologist @Compenstine might have an idea or two about what's going on with your juices.

In my experience, excessive heat tends to turn some juices a much darker color and can give it an "off" flavor just as Bebop said. I've had some juices that I liked a lot turn into an awful tasting concoction when I accidentally left a small carry bottle of it in the car on a hot day... oops!

Thank you for these answers. I will look forward to maybe getting a few more. I am glad that I came here and got to meet you on my first day here in VaporTalk Land. I too am going to try to study this issue a bit more and yes your answers mesh with what is going on here. Thanks again. TTYL
